Mister Electricidad

Mister Electricidad is a supporting character in The Adventures of Sharkboy and Lavagirl in 3-D, being the schoolteacher of both Max and Linus. Electricidad is a tough teacher oblivious to Max's feelings, ostracizing him for telling a story about his dreams as opposed to something he did in reality. However, Electricidad is not unreasonable, as he punishes Linus for harassing Max and his disrespectful attitude and forces him to return Max's Dream Journal, and is even willing to compliment Linus for finding a solution to his Shadow's attempt to overlay himself onto reality.
